Please open up an issue on the Magento 2 Github so the core team can investigate and fix this issue.
In the meantime you can try the following workaround.
Open up app/etc/di.xml
file and find the following xml snippet:
<virtualType name="developerMaterialization" type="Magento\Framework\App\View\Asset\MaterializationStrategy\Factory">
<arguments>
<argument name="strategiesList" xsi:type="array">
<item name="view_preprocessed" xsi:type="object">Magento\Framework\App\View\Asset\MaterializationStrategy\Symlink</item>
<item name="default" xsi:type="object">Magento\Framework\App\View\Asset\MaterializationStrategy\Copy</item>
</argument>
</arguments>
</virtualType>
Replace the above with the following by modifying the line that starts with <item name="view_preprocessed"
to use the Copy
strategy.
<virtualType name="developerMaterialization" type="Magento\Framework\App\View\Asset\MaterializationStrategy\Factory">
<arguments>
<argument name="strategiesList" xsi:type="array">
<item name="view_preprocessed" xsi:type="object">Magento\Framework\App\View\Asset\MaterializationStrategy\Copy</item>
<item name="default" xsi:type="object">Magento\Framework\App\View\Asset\MaterializationStrategy\Copy</item>
</argument>
</arguments>
</virtualType>
